H AY L O A D E R SPECIFICATION forming part of Letters Patent No.485,769, dated November 8, 1892.

' Application filed October 20, 1891. Serial No. 409,313- (No model.)

To all whom it may concern:

Be it known that I, JOHN L. MOCREARY, a citizen of the United States,residing at Lamar, in the county of Barton and State of Missouri, haveinvented a new and useful Hay-Loader, of which the following is aspecification.

This invention relates to hay-loaders, and more especially to that classthereof known as endless carrier, and the object of the same is toeffect certain improvements in devices of this character.

To this end the invention consists in the construction hereinafter morefully described and claimed, and as illustrated on the three sheets ofdrawings, wherein Figure l is a plan view of this improved device. Fig.2 is a right-side elevation. Fig. 3 is a central longitudinal section.Fig. 4 is a section through one end of the axle, its bearing in theframe, and the hub of the supporting-wheel. Fig. 5 is an enlargedvertical section through one of the bearings of the rear roller of theupper apron. Fig. (i is a cross-section through the upper rollers of thetwo aprons. Fig. 7 is a transverse section on the line 7 7 of Fig. 2.

Referring to the said drawings, 1 is the main axle, which, in thepresent instance, also forms the rake-head since the rake-teeth 2 dependfrom this axle, as seen in Fig. 3.

3 is a bar or lever projecting rearward from the axle, turned up, andstanding alongside the drivers seat 4, (if one be used,) a rackbar 5rising from the frame 6 alongside this lever and being engaged by thecatch 7 thereon, as will be clear. The ends 8 of the axle have annulargrooves 9, asseen in Fig. 4, which engage bearings 10, preferablylocatedon the under sides of the side bars of said frame and outside theenlargements or collars 11. The extremities of the axle are rounded, asat 12, and the supporting-wheels 13 are journaled thereon. By thisconstruction the axle is allowed to oscillate in its bearings in theframe and in the hubs of the wheel, and hence it may be turned by thelever to raise the teeth of the rake when desired. The said frame 6 isof any suitable construction; but, preferably, about as shown in thedrawings-that is to say, its side bars 14 extend forward and areconnected by a front bar 15. Depending from the rear ends of the sidebars are the rear bars 16, which incline forward, and from their lowerends inclined bars 17 rise past the side bars, as seen, vertical bars 18depending in turn from their front ends and being connected by a lowercross-bar 19. From the latter rises an auxiliary frame or framework 20,which rests on the front cross-bar and whose side bars are connected bycross-strips 21, which support a bottom board 22. The various portionsof this frame are connected and otherwise braced, as may be necessaryand according to the fancy of the manufacturer. A casterwheel 23 beneaththe lower cross-bar l9 supports the weight of the front end of themachine, though the machine is to be connected, as by chains 24, withthe rear end of a hay-wagon (not shown) and in order that the hay willbe delivered into said wagon, as is usual in machines of this character.

Mounted on strips 30, which connect the inclined bars 17, is a table 31,across whose upper and lower ends stand rollers 32 and 33, whose shaftsare suitably journaled in the frame, and over these rollers passes anendless apron, preferably composed of belts 34: at the ends of therollers, connected by slats 35 on the outer faces of the belts. Thelowerside of this apron passes beneath the strips 30," while its upper sidetravels upon the face of the table 31.

Journaled in bearings in the rear bars 16 and in the vertical bars 18are the shafts of rollers 36 and 37, the latter (37) being somewhathigher above the roller 32 than is the rear roller 36 above its roller33, and over these rollers 36 and 37 passes an upper endless apron,preferably comprising belts 38, at the ends of the rollers, connected byslats 39 on the outer faces of the belts. The bearings 40 for the roller36 are vertically elongated, as seen in Fig. 5, each shaft of the rollerstanding in a box 41 within the slotted bearing and borne normallydownward therein by aspring 42. Each of the front rollers 32 and 37preferably has an enlargement or pulley 43 just inside each of itsbearings, as seen in Fig. 6, and the belts of the aprons pass over thesepulleys, thus giving greater space between the centers of the rollersfor the passage of the hay.

7 in Fig. 1,is'about half the width of the other apron.

55 are braces connecting the framework 20 with the vertical bars 18, and56 are plates supported by these braces, secured at their lower edges tothe framework and forming guides about as shown.

On one end of the shaft of the roller 51 is a sprocket-wheel 60. Outsidethe bearing for this shaft and in alignment therewith is a smallsprocket-wheel 61 on the shaft of the roller 32 and a largersprocket-wheel 62 on the shaft of the roller 37.

63 is an upright rising from the frame, and 64 is an idle-wheel mountedon astub-shaft 65 in this upright. An endless chain belt 66 passes overa large sprocket-ring 67, secured to one of the supporting-wheels 13, asseen in Fig. 2, and extends thence over the idle-wheel 64, under thelarge sprocket 62, over the smaller sprocket 61, around the lowersprocket 60, and back to the point of starting, and by this means theproper motion is imparted to the several apronsthat is, thedelivery-apron moves upward over its table, as does the lower apron overits table, and the upper apron moves in an opposite direction to thelower apron, so that their adjacent sides travel in the same direction;but the upper apron moves 'more slowly than the lower, owing to thedifference in the sizes of the wheels 61 and 62.

The operation of this machine will be clearly understood by reference tothe above description when taken in connection with the drawings. Thehay which is taken up by the rake-teeth is caught by the two aprons andcarried up between them, movingin a direction transverse to the lengthof the grain. When it is dropped from the upper ends of these aprons, itfalls onto the plates 56, as will be clear. These plates are so curved'the one being raised and the other depressedthat the hay is turned bythe plates from its position transverse to the machine to a positionlongitudinal thereof-that is, so that it will lie longitudinally of theframework. As it falls on the latter between the inner edges of theplates the slats 54 catch the grain and carry it up to the hay-wagon, aswill be clear. In order that the endless belt 34 may successfully takeup and elevate the hay, it is made to travel faster than its companionbelt 38. The said belt 38, moving a little slower than the belt 34 andhaving longer teeth, serves to more equally spread the hay and arrangeit transverse the apron, so that it moves in a uniform mass. Bydiverging the belts toward their upper ends clogging at said ends isavoided, and any quantity capable of being taken in at the lower end ofthe carrier will be readily carried up and delivered from the carrier.

What is claimed as new is 1. In a hay-loader, the combination, w th theframe, the main axle journaled therein, the supporting-wheels journaledon the ends thereof, the curved teeth carried by the axle, and means foradjusting the angle of the teeth to the frame, of forwardly -incl1nedendlessaprons leading from a point just in front of the rake and havingtheir adjacent faces moving in the same direction, a small sprocket onone of the rollers of the lower apron, a larger sprocket on the rollerof the upper apron, a sprocket-ring on one of the driving-wheels, and achain belt passing over this ring, under the larger sprocket and overthe smaller sprocket, as and for the purpose Set forth.

2. In a hay-loader, the combination, with the gathering devices and anapron leading upwardly and forwardly therefrom, of a frame supportingthe whole, a framework leading upwardly and forwardly from a point belowthe upper end of said apron, an upwardlymoving delivery-apron in saidframework, braces connecting the frame and framework, and plates carriedby said braces above the lower end of the delivery-apron, one platebeing raised and the other depressed, so 'as to turn the grain a rightangle, substantially as described.

3. In a hay-loader, the combination, with the gathering devices, a broadapron leading upwardly therefrom, teeth carried thereby, and a framesupporting the whole, of a narrow framework carried by said frame andleading upwardly from a point thereon below the upper end of said apron,a narrow delivery-apron moving in said framework,

and plates below the upper end of the broad apron, one plate beingraised and the other being depressed, so as to turn the grain from itsposition across the broad apron to a position longitudinal of the narrowapron, substantially as hereinbefore described.

4. In a hay-loader, the combination, with gathering, elevating, anddelivering mechanisms, of intermediate fixed deflecting-plates arrangedat the head of the elevating mech anism, one of said plates beingelevated and the other depressed, substantially as specified.

5. In a hay-loader, the combination, with gathering mechanism, of anendless carrier located in front of same and comprising two endlessaprons arranged one above the other with their adjacent or facing sidesprovided with teeth traveling in the same direction at IIO In testimonythat *I claim the foregoing as my own I have hereto affixed my signaturein m the presence of two witnesses.
